Hey... I have to cut out return and supply openings in a basement spare
room from the duct that is already there on the ceiling (it's the end
of run for both s/r ducts that enter the room I made about 2 feet in).
They are square ducts. Can I make the openings in the *end* of the
ducts? Or do I have make the openings on the side? Any required
distance from the end (if side holes req.)? Just wondering, since I've
noticed that take-offs are always from the sides or top/bottom and
there's always a bit left over on the end--is that on purpose for
design or just to leave a bit for future use?
I know, it's basic, but you are the pros... hehehe
We found that side air is far superior to end air.
Either that, or taking a vent off the end provides a higher air flow
than from the side. So, we keep it fairly consistent.
As to your cellar, go ahead and try it.

You can\'t shout down a troll.
Yes and no. You have to properly size the return openings. If you
punch a big hole in the return close to the furnace and a bunch of
others further down the line on the return away from the furnace the
air is going to take the path of least resistance. It will try to pull
all its return from that big hole closest to the furnace.
Thanks folks.. I cut a hole in the end of the return and the side of
the supply. On the return end I put an adjustable flap so I can close
it enough to make a bigger resistance if necessary.... it sure is hard
to find proper covers for a 1950s 8x9" box... The "pros" at the shop
said it must be 8x10" and suggested I didn't measure right. Why are so
many people in this industry so damn rude and ignorant?????
Easy there boy... I didn't say ALL, nor did I imply anyone here; And
are you telling me that you've never gone to buy some parts from the
supply place and met with some idiot who refuses to accept what you're
telling them? Who treats you like you are more ignorant than he?
Hey, if these guys knew their stuff, maybe they wouldn't be salesmen...
